"Then I'll give it a try." According to the method provided by Ye Qing, Gu Changqing found two words that looked similar and moved them to the corresponding spaces.

Suddenly, the disc clicked one after another.

Seeing that there were no changes around him, Gu Changqing suddenly breathed a sigh of relief, and said in his heart: It seems to be right!

Immediately afterward, his gaze looked to the upper right of the disk, where there were still two spaces.

It's just that the left and right of these two spaces are no longer words, but numbers.

These numbers are not Arabic numerals, but the oldest kind of Roman numerals.

Although Gu Changqing loves mathematics, when he sees this kind of Roman numerals, he is also blinded.

How do you calculate this?

I don't understand!

"What is this?"

As the protagonist of Ye Qing, the three views have been refreshed again.

He's grown so big, he's never seen anything like this before!

No!

This shouldn't be called words,

It's just a symbol!

"What are these symbols? Is it also text? But it doesn't look like it! ”

"That's right!" Xu Zhiqian also wondered: "What is this painting?" ”

Gu Changqing coughed lightly twice and said, "According to my speculation, this should be the oldest arithmetic. ”

"Arithmetic??"

Ye Qing scratched his head, puzzled: "Master, arithmetic shouldn't look like this, right?" Aren't they also words? ”

Gu Changqing began to explain: "The arithmetic we learn is actually simplified, and it is not as complicated as what we see. This arithmetic, which should be regarded as the oldest one, is the first version invented by the creator. ”

"First version?" Ye Qing said with surprise on his face: "Oh my God! I originally thought that arithmetic is difficult enough to learn now, but when I saw the first version of arithmetic, I realized that arithmetic was even more difficult at that time! ”

"Arithmetic is skillful."

Gu Changqing smiled slightly: "As long as you master the skills, whether it is addition, subtraction, multiplication and division, it is not a problem." ”

As he spoke, he crouched down and carefully studied the two math problems on the ground.

Although Roman numerals are used here, the result is the same.

As long as you know the number represented by this symbol, you will be able to solve the corresponding answer.

"This is a ......"

"This is a three-......"

"Is this four or five?"

"This should be eight, right?"

Faced with math problems, Gu Changqing was engrossed.

Ye Qing and Xu Zhiqian, who were beside him, watched quietly, not even daring to take a breath.

I'm afraid I'll disturb him!

This kind of arithmetic problem is actually the most difficult, and basically not many people can fully learn it.

Those who learned to become officials have already gone to become officials!

With this kind of knowledge, if you ask for an official and a half-job, you won't have to worry about food and clothing in the next life.

"This should be nine ......"

"This is six......

Gu Changqing muttered and moved the square engraved with the number to the location of the space.

For a moment, there was a clattering sound from the disc.

The three of them hurriedly looked around, and immediately breathed a sigh of relief when they found that there was no movement.

It seems that the answer is right!

Immediately after, Gu Changqing filled the last space slot, and the disc clicked again.

When he stood up, the disc made a creaking sound, and then, the surrounding stone walls suddenly trembled, and a lot of dust fell, and at the same time, the stone door in front of the three of them slowly rose upward.

It's opened!

"It's finally open!"

Ye Qing exhaled a long breath and said with emotion: "It's really hard work that pays off!" ”

Then, the three of them walked towards the stone door.

With the help of the faint light of the black jade, the three of them found that behind the door was a secret room that was not very large.

It is surrounded by stone walls, on which are carved many portraits of monsters with teeth and claws, and some dense texts.

These words are all ancient characters, so none of the three of them can understand what they mean.

In the center of the secret room, there is a stone platform with a length and width of two meters, and the one above it is an ancient artifact.

It may be that sensing the three of them coming, the ancient artifact suddenly released a golden light, which was extremely dazzling.

In an instant, the whole secret room will be lit up!

"This is an artifact, right?"

Ye Qing said in surprise: "Master, this sword doesn't also refer to the fragments of the Heavenly Sword, right?" ”

Gu Changqing nodded slightly and said, "That's right! This sword should be the Sun-Chasing Sword! ”

Sun-chasing Sword –

The sword body is engraved with the sun and the moon, carrying the things of heaven and earth to the sun, because the whole body exudes a blazing breath, so it only takes a day character.

Later, because the divine power contained in its body was greater than that of the sun, it could make its light gradually dim, and it was extremely prosperous and could not be overcome.

So, it was named the day!

It is one of the three fragments of the ancient artifact Pointing Heavenly Sword, which has the power of the sun and can control the light of the universe.

"Such a powerful energy."

Xu Zhiqian couldn't help but sigh: "Standing here, it seems to be face to face with the sun, and there is a burning feeling. ”

"This is not its heyday." Gu Changqing said with a smile: "If its full power is exerted, then the entire heaven and earth will fall into a sea of fire." ”

"At that point, the real disaster will come."

As the author of the novel, Gu Changqing knows these ancient artifacts too well.

Although the Sunchaser Sword refers to the fragments of the Heavenly Sword, the energy it contains is the most powerful of the three fragments.

In other words, the Sun-Chasing Sword is the backbone, and having it is equivalent to having half of the Pointing Heaven Sword.

However, if you want to synthesize the Fingering Sky Sword, you still need three fragments together, and you can't miss one.

But if you can control the Sun-Chasing Sword and exert its full power, then the result is still quite terrifying.

It is no exaggeration to say that the energy of the Sun-Chasing Sword is simply like the sun hitting the blue star!

It's incredibly powerful!

"Master, I'll take it down!"

Ye Qing said with a light smile, and then walked quickly towards the position of the stone platform.

However, just as his right hand was about to touch the hilt of the Sun-Chasing Sword, a powerful heat suddenly swept across his face.

Blowing so much that he can't open his eyes!

"What's going on?"

"It's so dazzling!"

After seeing this scene, Gu Changqing hurriedly ran forward, grabbed Ye Qing's arm without saying a word, and pulled him back.

At the same time, the light of the Sunchaser Sword gradually dimmed, returning to its previous form.

"This sword has psychic powers?"

Xu Zhiqian said with a shocked face: "How is it possible? Isn't this a fragment of the Heavenly Sword? How can spiritual consciousness be born? ”

Gu Changqing shook his head slightly and said, "I don't know very well. The reason why the energy of the Sun-Chasing Sword is so powerful may be because of the spiritual consciousness born in its body, right? ”

"In that case, how are we going to take it down? Tame it? But it's too late! ”

In this regard, Gu Changqing frowned.

He was thinking in his mind, how did the protagonist Ye Qing win this Sun-Chasing Sword in the first place?

Hard to take?

But I've tried it just now, and ordinary people can't get close to the Sun Chasing Sword at all.

Once you get close, you will be burned by the fiery power it unleashes.

So......

What method did Ye Qing use?

……
